Virtual machine cannot start，TASK ERROR: timeout: no zvol device link for

[tdyun]

Today I rebooted the server and one of the VMs won't boot after that. I tried many methods but nothing worked. I detached the disk and it won't reload: update VM 1265: -scsi0 local-zfs:vm-1265-disk-0,iothread=on
TASK ERROR: timeout: no zvol device link for 'vm-1265-disk-0' found after 300 sec.

it looks to me like the zvol is in the wrong dataset? assuming "local-zfs" is the default ZFS storage on "rpool/data"... did you do any manual syncing or something like that?
